State airport operator PT Angkasa Pura I is readying to expand Ngurah Rai International Airport in Bali, saying it will organize a tender for the first phase of the project soon.

The expansion has been estimated to require up to Rp 1.9 trillion (US$ 210 billion) in investment and is scheduled for completion by 2013.

“The project will be separated into four phases. We are ready to commence the first phase, disbursing Rp 227.7 billion in investment,” Angkasa Pura I planning director Yuda Prana Sugarda said in Jakarta on Wednesday, adding that during the first phase the company would construct access roads and substitute buildings.

The second phase will require Rp 344 billion, while the third and fourth phases will cost Rp 1.2 trillion and Rp 100 billion, he said.

Of this amount, up to Rp 1.2 trillion will be financed by the state and the government investment center, involving three state banks — Mandiri, BNI and BRI. The remainder will be taken from the company’s cash reserves.

According to an earlier report, under the planned expansion Angkasa Pura would switch the domestic and international terminals to cope with an increase in international passengers.

The new international terminal would also be expanded to cover 120,000 square meters.

The management also plans to build a 39,000-square-meter three-story parking with room for up to 1,500 vehicles.

By 2013, the airport’s terminals will cover 190,000 square meters and be able to serve up to 20 million passengers a year.
